Question

我遇到了一次解析两个JSON网址的问题。 YouTube每次请求只允许50个结果，因此我想添加一个起始索引为51的秒，以继续请求。

NSString *urlAsString  = @"https://gdata.youtube.com/feeds/api/playlists/PLgw1uRYia2CRvuF4Y3KLuvFSWY6lmuY8T?v=2&alt=json&max-results=50&orderby=published";
NSString *urlAsString2 = @"https://gdata.youtube.com/feeds/api/playlists/PLgw1uRYia2CTSBBNrTDjdEcswVFjPkCr9?v=2&alt=json&max-results=50&orderby=published";

结合其中两个，我尝试了这个：

NSString *finallink = [NSString stringWithFormat:@"%@,%@", urlAsString, urlAsString2];

然后用Afnetworking提出实际请求，我补充道：

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    [manager GET:finallink parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {

        manager.requestSerializer = [AFHTTPRequestSerializer serializer];
        manager.responseSerializer = [AFHTTPResponseSerializer serializer];

        NSDictionary *feed = [[NSDictionary alloc] initWithDictionary:[responseObject valueForKey:@"feed"]];
        videoArray = [NSMutableArray arrayWithArray:[feed valueForKey:@"entry"]];
        [self.videoMetaData  addObjectsFromArray:[videoArray valueForKeyPath:@"title.$t"]];

        operation.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];

        [self.videolist reloadData];
        [self->activityind startAnimating];



        NSLog(@"JSON: %@", responseObject);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {

        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error Retrieving Videos"
                                                            message:[error localizedDescription]
                                                           delegate:nil
                                                  cancelButtonTitle:@"Ok"
                                                  otherButtonTitles:nil];
        [alertView show];
        NSLog(@"Error: %@", error);
    }];

由于某种原因，这不起作用。我收到这个错误：

Error: Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)"

可能有什么不对？！
